[users@httpd] Apache 2.0 Buffered I/O API question
I am converting a custom module that is written in C for Apache 1.3. Due
to the lack of documentation for the Apache 2.0 API
I am forced to pull my hair out. :)
I came across a set of functions in the Apache 1.3 API but I can't find
them or their equivalent in the new 2.0 APIs :
http://www.hk8.org/old%5Fweb/linux/....htm#INDEX-1512
for example
14.6.22. Buffering Functions
Apache provides its own I/O buffering interface. This allows
chunked transfers to be done transparently and hides differences
between files and sockets under Win32.
ap_bcreate create a buffered stream
BUFF *ap_bcreate(pool *p, int flags)
Creates a new buffered stream in p. The stream is not associated
with any file or socket at this point. flags are a combination of one of
the following:
These set of functions is completely missing from the new Apache 2.0 API.
Does anybody know what they are replaced with.
Thanks in advance.

i have looked at apr_network_io.h.
i don't see anything that offers the same ability as the
ap_bcrete() or ap_pushfd() did.
Does this mean i have to write to the socket using apr_socket_send()?
this is much less convinient then the old way.
do you know any other alternatives?
Thanks

Oh, you mean IPC unconnected with the request/response?
That's now APR, not HTTPD. Look at apr_network_io.h.

This is what I have right now in a module for ver 1.3 that I am trying to
convert to 2.0 API
buffer = ap_bcreate( r->pool, B_RDWR );
ap_bpushfd( buffer, socket, socket );
>From what I understand this creates a i/o buffer in the pool with READ and
WRITE permissions. Then with ap_bpushfd it connects the buffer to the
read/write streams of the socket.
To print to the socket I do something like
ap_bprintf( buffer, "Hello %s!\r\n", name);
Since ap_bcreate() is missing from 2.0 API, how would I convert this properly
to the new 2.0 API.
Thanks

Not unless you tell us what you need that isn't provided for by the
ap_rwrite() and/or ap_fwrite() family of buffered IO functions.
